Why is the 70th week of Daniel still future?

What scriptural reason is there for stating as a fact that the seventieth week was cut off from the rest and is yet to be fulfilled?

The scriptural reason is understood by reading the passage (Daniel 9:24-27). The seventy “hebdomads,” or periods of seven years are said by Gabriel to be “determined upon Daniel’s people (the Jews) and the holy city, to punish the transgressors. . . and to anoint the Most Holy.” Then, in verse 25, this whole period of 490 years is resolved into its constituents of 49 years (during which building operations were completed), then a further 434 years to the cutting off of the Messiah, that is 483 years in all, or 7 years short of the total 490. Why is this? Because as Zechariah 11:10 tells us, when “the staff, even Beauty,” is cut off (a description of the same event as the cutting off of Messiah), Jehovah’s covenant, which he had made with all the people, is broken, so that one period of seven years, or one “hebdomad,” still remains to be fulfilled. This will have its place when the prince of the people who destroyed the city (the Romans in 70 A.D.) will confirm a covenant with many for one week or period of seven years. The fact that He will break His covenant in the middle of the period, i.e., after 3 1/2 years, will not override the fact that this “hebdomad” will complete the 490 years determined on the Jews, to end with “anointing the Most Holy,” which will take place when Christ returns in glory to reign.
